Genetically modified cassava is currently being developed to address problems of diseases that threaten the food security of farmers in developing countries. The technologies are aimed at smallholder farmers, in hopes of reducing the vulnerability of cassava production to these diseases. In this paper we examine barriers to farmers’ voice in the development of GM cassava. We also examine the role of a translational research process to enhance farmers’ voice, to understand the sources of vulnerability farmers in a group in (...) Kenya’s Coast face, and to determine if their concerns are consistent with those of the scientists in agriculture addressing farmers’ needs. A two-way communication participatory process provided insights into the complex vulnerability context of farmers, their primary concerns with processing and markets of cassava in order to improve livelihoods, the lack of networks with two way communication flows, and the lack of information on GM technologies. The translational research engaged farmers and scientists in an iterative process where scientists are learning what farmers need, and farmers are learning about the potential benefits and risks from GM technologies, while at the same time expressing their concerns.

In most areas of our lives, legal protections are in place to ensure that we have autonomous control over what happens in and to our bodies. However, there are fewer protections in place for autonomous choice when it comes to the food we purchase and consume. In fact, the current trend in US legislation is pushing us away from autonomous food choice. In this paper, I discuss two examples of this trend: corporate resistance to GM labeling laws and farm protection (...) laws. These examples are quite different from a legislative point of view. In one case, laws that would promote autonomous choice are actively resisted, whereas in the other case, laws that undermine autonomy are enacted. The common core of the two examples is the effect: in both cases, we are unable to determine whether the food we purchase and consume is consistent with our values. In both cases, then, autonomous choice about the food we purchase and put into our bodies is undermined. (shrink)

At a time when agri-food biotechnologies are receiving a surge of investment, innovation, and public interest in the United States, it is common to hear both supporters and critics call for open and inclusive dialogue on the topic. Social scientists have a potentially important role to play in these discursive engagements, but the legacy of the intractable genetically modified (GM) food debate calls for some reflection regarding the best ways to shape the norms of that conversation. This commentary argues that (...) agri-food scholars interested in promoting a more constructive agri-food biotechnology discussion could do so by blending key insights, as well as guarding against key shortcomings, from the fields of science communication and science and technology studies (STS). Science communication’s collaborative and translational approach to the public understanding of science has proven pragmatically valuable to scientists in academia, government, and private industry, but it has too often remained wedded to deficit model approaches and struggled to explore deeper questions of public values and corporate power. STS’s critical approach has highlighted the need for multi-stakeholder power-sharing and the integration of diverse knowledge systems into public engagement, but it has done little to grapple with the prevalence of misinformation in movements against GM foods and other agri-food biotechnologies. Ultimately, a better agri-food biotechnology conversation will require a strong foundation in scientific literacy as well as conceptual grounding in the social studies of science. The paper concludes by describing how, with attention to the structure, content, and style of public engagement in the agri-food biotechnology debates, social scientists can play a productive conversational role across a variety of academic, institutional, community-level, and mediated contexts.

Future technological developmentsconcerning food, agriculture, and theenvironment face a gulf of social legitimationfrom a skeptical public and media, in the wakeof the crises of BSE, GM food, and foot andmouth disease in the UK (House of Lords, 2000). Keyethical issues were ignored by the bioindustry,regulators, and the Government, leaving alegacy of distrust. The paper examinesagricultural biotechnology in terms of a socialcontract, whose conditions would have to be fulfilled togain acceptance of novel applications. Variouscurrent and future GM applications areevaluated against these (...) conditions. Successwould depend critically on how far a sharedvision can be found with the public. Tore-establish trust, significant changes areidentified in the planning and pursuit ofbiotechnology. (shrink)

The production of genetically modified crops is growing around the world, and with it possible opportunities to combat food insecurity and hunger, as well as solutions to current problems facing conventional agriculture. In this regard the use of GMOs in food and agricultural applications has increased greatly over the past decade. However, the development of GM crops has been a matter of considerable interest and worldwide public controversy. This, in addition to skepticism, has stifled the use of this practice on (...) a large scale in many areas, including Iran. It stands to reason that a greater understanding of this practice could be formed after a review of the existing expert opinions surrounding GM crops. Therefore, the purpose of this study was to analyze the predictors that influence agricultural experts’ attitudes toward the development of and policies related to GM crops. Using a descriptive correlational research method, questionnaire data was collected from 65 experts from the Agricultural Organization in the Gotvand district in Southwest Iran. Results indicated that agricultural experts were aware of the environmental benefits and possible risks associated with GM crops. The majority of participants agreed that GM crops could improve food security and accelerate rural development, and were proponents of labeling practices for GM crops. Finally, there was a positive correlation between the perception of benefits and attitudes towards GM crops. (shrink)

A high percent of oxidative energy metabolism is needed to support brain growth during infancy. Unhealthy diets and limited nutrition, as well as other environmental insults, can compromise these essential developmental processes. In particular, iron deficiency anemia has been found to undermine both normal brain growth and neurobehavioral development. Even moderate ID may affect neural maturation because when iron is limited, it is prioritized first to red blood cells over the brain. A primate model was used to investigate the neural (...) effects of a transient ID and if deficits would persist after iron treatment. The large size and postnatal growth of the monkey brain makes the findings relevant to the metabolic and iron needs of human infants, and initiating treatment upon diagnosis of anemia reflects clinical practice. Specifically, this analysis determined whether brain maturation would still be compromised at 1 year of age if an anemic infant was treated promptly once diagnosed. The hematology and iron status of 41 infant rhesus monkeys was screened at 2-month intervals. Fifteen became ID; 12 met clinical criteria for anemia and were administered iron dextran and B vitamins for 1–2 months. MRI scans were acquired at 1 year. The volumetric and diffusion tensor imaging measures from the ID infants were compared with monkeys who remained continuously iron sufficient. A prior history of ID was associated with smaller total brain volumes, driven primarily by significantly less total gray matter and smaller GM volumes in several cortical regions. At the macrostructual level, the effect on white matter volumes was not as overt. However, DTI analyses of WM microstructure indicated two later-maturating anterior tracts were negatively affected. The findings reaffirm the importance of iron for normal brain development. Given that brain differences were still evident even after iron treatment and following recovery of iron-dependent hematological indices, the results highlight the importance of early detection and preemptive supplementation to limit the neural consequences of ID.

The character of the current controversy over geneticallymodified (GM) agriculture, typified by protesters' use of emotivesymbolism, has been largely inspired by the Green movement'snon-governmental organizations and political parties. This articleexplores the deeper philosophical and spiritual motivations of the Greenmovement, to inquire why it is implacably opposed to GM agriculture. TheGreen movement's anti-capitalism, exemplified by the hate-symbol statusof Monsanto as the company pioneering GM crops, is viewed within thewider context of alienation in the modern era. A complex of meanings isseen in (...) Frankenstein as the focal symbol of GM protests, includingperceptions of risk, fears of the remixing of living identities seen ingenetic engineering, and resentment at the spiritual nihilism of thereduction of life to the digital code of DNA. By contrast, RobertGoodin's Green Theory of Value, which postulates the deep psychologicalimportance of nature in locating the self in a meaningful context largerthan ourselves, can explain the power of the Green symbol of thethreatened environment, Gaia. The advent of GM agriculture seems toimply that capitalism and technology can now enframe nature itself,leaving a world devoid of natural myth or meaning, with no escape fromthe alienation and nihilism of modernity. The central question posed forprotagonists of the GM debate is whether their agenda is based on thesepowerful but mythical conceptions of the environment, or whetherpreservation of the real environment is their primary ethic.

IntroductionThe pelvic floor muscles are active during motor tasks that increase intra-abdominal pressure, but little is known about how the PFM respond to dynamic activities, such as gait. The purpose of this study was to characterize and compare PFM activity during walking and jogging in continent adults across the entire gait cycle.Methods17 able-bodied individuals with no history of incontinence participated in this study. We recorded electromyography from the abdominal muscles, gluteus maximus, and PFM while participants performed attempted maximum voluntary contractions (...) of all muscles and completed 60–70 strides in four gait conditions: slow walk ; regular walk ; transition walk ; jog. We quantified activity throughout the whole gait cycle and during periods of bursting for each participant, and analyzed the timing of PFM bursting periods to explore when the PFM were most active in the gait cycle. We also conducted a phase metric analysis on the PFM and GM burst timings. We performed a Spearman's rank-order correlation to examine the effect of speed on %aMVCGC, %aMVCBR, and phase metric score, and used the Wilcoxon Signed-Rank test to evaluate the effect of gait modality, matched for speed, on these variables.ResultsThe PFM were active throughout the gait cycle, with bursts typically occurring during single-leg support. The PFM and GM were in phase for 44–69% of the gait cycle, depending on condition. There was a positive correlation between gait speed and both %aMVCGC and %aMVCBR. Phase metric scores were significantly higher during jogging than transition walking, but there was no difference between gait modality on %aMVCGC or %aMVCBR. Where possible we disaggregated data by sex, although were unable to make statistical comparisons due to low sample sizes.ConclusionThe PFM are active during walking and jogging, with greater activity at faster speeds and with bursts in activity around single-leg support. The PFM and GM co-activate during gait, but are not completely in phase with each other. (shrink)

It's surprising that contemporary moral philosophers have not thought more about food. The rapidly expanding industrialized landscape of modern western agribusiness raises moral concerns about large-scale livestock production, the increased usage of genetically modified crops, and the effects these now common practices may have on long-term environmental and human health. Here Pence argues that biotechnology is more helpful than harmful, on the ground that it will abate world hunger. Positioning himself as an "impartialbioethicist" he sets about the task of sorting (...) through the extremism he thinks drives all environ- mental movements' opposition to genetically modified (GM) crops. His argu- ment is simple: the claim that GM foods are unsafe is the product of alarmism, not sound reason. Discarding what environmentalists have called the Precau- tionary Principle, he argues that GM foods are safe because they have not been proven unsafe. And GM foods have been tested more than many food products now on the market. (shrink)

In aging humans, aerobic exercise interventions have been found to be associated with more positive or less negative changes in frontal and temporal brain areas, such as the anterior cingulate cortex (ACC) and hippocampus, relative to no-exercise control conditions. However, individual measures such as gray-matter (GM) probability may afford less reliable and valid conclusions about maintenance or losses in structural brain integrity than a latent construct based on multiple indicators. Here, we established a latent factor of GM structural integrity based (...) on GM probability assessed by voxel-based morphometry, magnetization transfer saturation, and mean diffusivity. Based on this latent factor, we investigated changes in structural brain integrity during a six-month exercise intervention in brain regions previously reported in studies using volumetric approaches. Seventy-five healthy, previously sedentary older adults aged 63–76 years completed an at-home intervention study in either an exercise group (EG;n= 40) or in an active control group (ACG;n= 35). Measures of peak oxygen uptake (VO2peak) taken before and after the intervention revealed a time-by-group interaction, with positive average change in the EG and no reliable mean change in the ACG. Significant group differences in structural brain integrity changes were observed in the right and left ACC, right posterior cingulate cortex (PCC), and left juxtapositional lobule cortex (JLC). In all instances, average changes in the EG did not differ reliably from zero, whereas average changes in the ACG were negative, pointing to maintenance of structural brain integrity in the EG, and to losses in the ACG. Significant individual differences in change were observed for right ACC and left JLC. Following up on these differences, we found that exercising participants with greater fitness gains also showed more positive changes in structural integrity. We discuss the benefits and limitations of a latent-factor approach to changes in structural brain integrity, and conclude that aerobic fitness interventions are likely to contribute to brain maintenance in old age.

A Study on Church in the Contemporary World after Card. Georges M. Cottier.

Kant, Schleiermacher, Hegel puis Feuerbach, Marx, Freud ou, plus près de nous, Jacques Bouveresse et Régis Debray : la philosophie de la religion s'est instituée avec la modernité pour tâcher de définir quelle peut être l'essence du fait religieux. Dans le sillage des Lumières, ses principaux représentants ont considéré comme un préalable absolu à leurs travaux la négation de la Révélation. Rien n'est moins sûr qu'ils aient eu raison. A preuve, sous les feux de l'actualité, le besoin d'une herméneutique intégrale (...) est toujours plus pressant. C'est à cette tâche que, au bout d'une vie consacrée à penser, s'est attelé le cardinal Cottier qui a longtemps exercé le métier unique de "théologien du pape" qui consiste à être l'ultime interlocuteur de l'évêque de Rome pour tout ce qui relève de la doctrine. Revenant de manière innovante à l'épistémologie élaborée par Thomas d'Aquin, qui n'entend rien ignorer ni de la raison ni de la foi, le dernier grand témoin de Vatican II montre ici que cette disjonction est contingente et que cette discipline représente une branche féconde et prometteuse du savoir philosophique, qui attend d'être pleinement développée. Un essai décisif pour un début de siècle tourmenté par le retour du religieux que doivent lire d'urgence tous ceux qui sont soucieux de refonder la culture humaniste dans son universalité. (shrink)
